As used in this subsection (4), “prima facie evidence” means evidence which is sufficient proof that the speed was not reasonable or prudent under the conditions then existing, and which will remain sufficient proof of such fact, unless contradicted and overcome by evidence bearing upon the question of whether or not the speed was reasonable and prudent under the conditions then existing.

(b) 
Reserved.
(2)

(3) 
The City shall determine upon the basis of a traffic investigation or survey the proper speed for all arterial streets and shall declare a reasonable and safe speed limit thereon which may be greater or less than the speed specified under GJMC § 10.04.1101(2)(b) or (2)(c). Such speed limit shall not exceed 75 miles per hour and shall become effective when appropriate signs are erected giving notice thereof. For purposes of this subsection (3), an “arterial street” means any United States or State-numbered route, controlled-access highway, or other major radial or circumferential street or highway designated by the City as such as part of a major arterial system of streets or highways.
(4) 
Upon the City’s request, the Department of Transportation shall conduct any traffic investigation or survey that is deemed to be warranted for determination of a safe and reasonable speed limit on any street or portion thereof that is a State highway. In conducting such a traffic investigation, the Department may receive and consider traffic and engineering data provided by the City or Mesa County Engineer that will be impacted by a proposed alteration of speed limits. Any speed limit so determined by the Department becomes effective when declared by the City and made known by official signs conforming to the State traffic control manual.
(5) 
Whenever the Department of Transportation or the City, within their respective jurisdictions, determine upon the basis of a traffic investigation or survey that a reduced speed limit is warranted in a school or construction area or other place during certain hours or periods of the day when special or temporary hazards exist, the Department or the City may erect or display official signs of a type prescribed in the State traffic control manual or City adopted traffic control manual giving notice of the appropriate speed limit for such conditions and stating the time or period the regulation is effective. When such signs are erected or displayed, the lawful speed limit at the particular time and place shall be that which is then indicated upon such signs; except that no such speed limit shall be less than 20 miles per hour on a State highway or other arterial street as defined in subsection (3) of this section nor less than 15 miles per hour on any other road or street, nor shall any such reduced speed limit be made applicable at times when the special conditions for which it is imposed cease to exist.
(6) 
The City may impose and enforce stop sign regulations and speed limits, not inconsistent with the provisions of GJMC § 10.04.1101 to 10.04.1104, upon any way which is open to travel by motor vehicles and which is privately maintained in mobile home parks and/or private street, when appropriate signs giving notice of such enforcement are erected at the entrances to such ways. Unless there is an agreement or other law or regulation to the contrary, the City shall be responsible for the erection and maintenance of the signs.
(7) 
When a reduced speed is authorized consistent with the provisions herein, a violation of the altered speed is a violation of GJMC § 10.04.1101(2)(h).
(Ord. 4759, 9-6-17)
(1) 
No person shall drive a motor vehicle on any highway at such a slow speed as to impede or block the normal and reasonable forward movement of traffic, except when a reduced speed is necessary for safe operation of such vehicle or in compliance with law.
(2) 
When the City determines, on the basis of an engineering and traffic investigation as described in the State/City traffic control manual, that slow speeds on any part of a highway consistently impede the normal and reasonable movement of traffic, the City may determine and declare a minimum speed limit below which no person shall drive a vehicle, except when necessary for safe operation or in compliance with law.
(3) 
Notwithstanding any minimum speed that may be authorized and posted pursuant to this section, if any person drives a motor vehicle on any controlled-access highway at a speed less than the normal and reasonable speed of traffic under the conditions then and there existing and by so driving at such slower speed impedes or retards the normal and reasonable movement of vehicular traffic following immediately behind, then such driver shall:
(a) 
Where the width of the traveled way permits, drive in the right-hand lane available to traffic or on the extreme right side of the roadway consistent with the provisions of GJMC § 10.04.1001(2) until such impeded traffic has passed by; or
(b) 
Pull off the roadway at the first available place where such movement can safely and lawfully be made until such impeded traffic has passed by.
(4) 
Wherever special uphill traffic lanes or roadside turnouts are provided and posted, drivers of all vehicles proceeding at less than the normal and reasonable speed of traffic shall use such lanes or turnouts to allow other vehicles to pass or maintain normal traffic flow.

(2) 
The City upon its own initiative may conduct an investigation of any bridge or other elevated structure constituting a part of a highway, and, if it finds that such structure cannot with safety to itself withstand vehicles traveling at the speed otherwise permissible under GJMC § 10.04.1101 to this section, the City or Department of Transportation shall determine and declare the maximum speed of vehicles which such structure can withstand and shall cause or permit suitable standard signs stating such maximum speed to be erected and maintained before each end of such structure in conformity with the State/City traffic control manual.
(3) 
Upon the trial of any person charged with a violation of this section, proof of said determination of the maximum speed by said Department and the existence of said signs shall constitute conclusive evidence of the maximum speed which can be maintained with safety to such bridge or structure.
